Engineering Contradiction Analysis
1Stability of the object's composition
If conventional systems combine battery and capacitor systems for voltage support, then voltage stability is improved, but circuit complexity increases leading to reduced reliability and increased cost
Solution Approach 1:
The system divides the voltage support function into two separate branches: one dedicated to battery system connection and another dedicated to capacitor system connection. Each branch has its own charging circuit, allowing independent operation and simplifying the overall control logic while maintaining voltage stability through coordinated operation of both branches
Solution Approach 2:
The parallel branch configuration enables the system to serve multiple functions: the first branch handles battery charging and voltage support, while the second branch handles capacitor charging and additional voltage support. This multi-functional design achieves voltage stability without requiring complex switching or control circuitry
2Power
If capacitor systems are used to provide sudden current demands, then power performance is improved, but voltage may exceed tolerance limits
Solution Approach 1:
The controller continuously monitors the output voltage and uses this feedback to control the charging circuits. When voltage approaches maximum limits, the controller regulates the charging current to prevent overvoltage conditions, allowing the capacitor system to provide high power while maintaining voltage within safe tolerance ranges
3Use of energy by moving object
If battery system provides energy storage, then energy performance is improved, but response time to sudden current demands increases
Solution Approach 1:
The system merges the energy storage capability of the battery system with the high power, fast-response capability of the capacitor system in a parallel configuration. The battery provides sustained energy while the capacitor delivers immediate current bursts, achieving both energy performance and fast response time simultaneously
